Optical and auditory illusions are working on different principles than free will.
No they do not! It is all the product of physical processes within the grey cells in the brain.
We could just as well proclaim gravity is an illusion and put up an MC Escher stair pic as a 'proof'. It doesn't prove anything.
Well.... let's have a look at this statement of yours more closely....
- We did not know that gravity existed for most of our lives
- Many people still deny it
- We still do not really understand it despite the most brilliant minds trying
- If you never go into outer space you would never feel it
- And the illusion is ... that you do not even know it exists... that is the illusion... the illusion is that despite spinning at 1000 mph and at the same time hurtling through space at 68,000+/- mph you have absolutely no idea that is hapenning
- Christians burned people alive for discovering the above facts because they could not believe their god could do that
So your analogy fails.... gravity is an illusion that has been dispelled by facts of physics.... just like free-will.
Free will is generally understood as something like 'the capacity of agents to choose between different possible courses of action unimpeded', or to have independent agency over your fate. Legal systems worldwide function on whether an individual has free will, otherwise they could not be held accountable, as they had no choice. Even yea verily this very forum would serve no purpose, as argumentation would be pointless. We could not agree or disagree, or even change our minds without free will.
Yes we can.... because our decisions are an
INTERACTION with outside influences at that instant as well as the
STORED SUM TOTAL of our previous
INTERACTIONS and trajectories taken due to those interactions... as well as the the genetic makeup ... which itself is the sum total of
INTERACTIONS made by other gene bags.
So to claim that we don't have free will is pretty much a fringe belief, that needs the proverbial extraordinary evidence.
Yes the extraordinary evidence is called Neurobiology... Chemistry... Physics... microbiology... and Genetics... DNA... etc. etc. etc.
Rejecting that is akin to the Catholic Church rejecting Heleocentricity.
Can anyone provide what they consider solid evidence that this commonly understood state doesn't exist?
The problem with commonsense... is that it is common... not to mention it is an ad populum fallacy....
The catholic church also asked the same question of Galileo Galilee while they were burning Giordano Bruno and Banning the writings of Kepler and Copernicus.
No changing the subject, or passing the buck, or shifting the burden, or other word games. And toying with 'unencumbered' choice doesn't mean anything; we are all influenced by environmental/genetic factors. Those may predispose us to a particular conclusion or increase the probability of reaching one, but it does not negate free will.
We are sure the brain is physical and its neuronal firings are physical and they are the result of the
DNA that made all the lipids and proteins in it and the chemicals it has acquired from the blood which has acquired them from the environment.
What we are not sure about is how we store the memory that we use as a
feedback mechanism (see image below) to influence the firing process in addition to the chemicals.
But those are the sum total of all the previous firings due to previous firings and chemicals.
At every instant the brain is at a state that has been set by previous states and current environmental factors (see image below)
None of this is freely willed by the definition of this term.
Where one is born ... at what era of time... to whom ... and how... is a random set of environmental factors that start a trajectory jump off point that is not in anyway under the control of the person being born
And from that point onwards each neuronal firing is the result of a feedback mechanism that depends on the environment at the moment of firing as well as the state of the brain which is the result of the previous states.
A path of which not a single point is freely willed.
